Emma Stone's Incredible Lip-Synching and More Unmissable Moments from Last Night's Late-Night TV

While you were sleeping last night, late-night TV was blowing up with must-see segments. The wee hours had it all: industry-shifting news, giggly girl time, and mind-blowing musical performances (minus the singing—you'll see). Let's break it down.

Business first: Craig Ferguson announced that he will step down from The Late Late Show at the end of this year. This is a double blow to fans who were upset that Ferguson didn't get David Letterman's job (Stephen Colbert did). But: Need I belabor this point again? This presents the perfect opportunity to finally funnel a woman into the late-night game. Please.__

Now onto pleasure, i.e., Cameron Diaz and Leslie Mann on WWHL. Do these two realize they'll eventually have to stop promoting The Other Woman and go back to their separate lives? I feel like they're going to be really upset. Case in point: their chemistry in this after-show clip.
